try using only the corsair ram. two identical ram is better. diff combination of ram speed and size might be the culprit of instability
try run aida64 memory bench to find which setting (4GbX2 + 1GbX2 VS 4GbX2 OC) has better score
example aida mem bench


cpuz memory and SPD tab


IMC speed is cpu-nb speed/ frequency aka NB freq.

the best is try find your ram limit 1st. use lower cpu multiplier. set the HT link near to 2Ghz and below.
set the ram timing at 9-9-9 at 1.6Vdimm. increase the fsb aka HTT step by step.
IMC / cpu-nb speed oso set near to 2Ghz and below. find the highest speed that your ram can go with
timing 9-9-9 @ 1.6Vdimm. good luck

with all dimm slot occupied, u mite wanna consider runnin d sticks @ 2t. it's hard to run 1t with 4 sticks when freq is at 1600Mhz or above.

try oc to 1600Mhz & success to boot to window, here the benchmark using aida64

10GB (2x4GB Cosair Vengeance + 1x2GB Kingston)



8GB 1333



8GB OC to 1600 with 9-9-9-24-41 voltage set to 1.57



manage to boot window but crash after 15 minutes, any advice?

crash as in auto reboot or BSOD?

BSOD bro, any advice?

disable auto restart & jot down d error code:

Common BSOD Error Code List for Overclocking

*credits to overclock.net

back to 1333 again with a bit tight timing 7-7-7-23-33-1T voltage is 1.6v



dont know stable or not

wow straight 1333 CL7
try using latest aida. cannot see some score there

its not stable bro, BSOD
dont know how to make my oc stable i even raise my voltage to 1.6v also BSOD, now back to standard setting

your ram spec is 1.5 @ 1333 CL9? post your cpuz>memory tab here

yes thats is my ram spec & below is my OC to 1600, no facing BSOD as i didnt stress it yet

good. btw you don't need to loose the timing above CL9. no points running 1600 on CL11
default 1333 CL9 @ 1.5Vdimm, perhaps you need to pump vdimm if you wanna run the ram at 1600 CL9.
most ram with good manage to do 1600 CL7 with 1.6Vdimm and below. if you cannot set 1600 CL9 with
lower then 1.6Vdimm, consider you have a not OCable ram edy.. this is where the poison start.

if you really wanna have fun with ram OC, try find 1600Mhz 4GbX2 with CL9 at 1.5V,
or 1600 (CL7, CL8) at 1.5-1.6V

apart of ram OC, you oso can OC the cpu-nb speed a.k.a IMC speed.

look at your cpuz>memory tab, got NB frequency. if you are using non-BE proc,
you need to increase the FSB to increase the cpu-nb speed

1600 OC 10-10-10-27-41 stress for 30 minutes stable



this time wanna try CL9

try run 1600 CL9-9-9 bro. CL10 not nice at that speed.. even 2133Mhz people run at CL9-10-9
more tight is better.
* tight : 1600 CL7-7-7, CL8-8-8
* loose : 1600 CL9-9-9, CL10-10-10

what is the ram voltage for 1600 CL10 there

This post has been edited by lengchai86: May 5 2012, 01:06 AM

i leave ram volatge at auto for 1600 CL10 & its stable, now im running stress for CL9, 1st i try set voltage at 1.55v 3 minute BSOD, raise to 1.6v cant boot to window then lower to 1.53v 1 minutes BSOD too now i try at 1.51v 10 minutes on running stress still stable until now wanna see its stability for half an hour stress..
now i learn 1 thing from my OC, over voltage is not good, must set the right voltage to make my OC stable

waaa i have to shoot wedding event this morning now at 1.30am still OC my ram, u r rite lengchai86, OC ram is very poison & fun

looks like your ram cannot accept moderate voltage..
most ram with good chip have no problem with 1.65Vdimm at 1600-1800 CL8
try yours with CL8 at lower than 1.55Vdimm

ram with good chip can run 2133 CL7 @ 1.65V
the lower the voltage at higher speed + tight timing is what everybody want

erk thats mean my ram chip is not that good? forgot to tell my ram is Vengeance LP version

23 minutes stress still stable , now its time for CL8

This post has been edited by makaroni: May 5 2012, 01:43 AM

mybe better if can 1600 CL8 with 1.52-1.52Vdimm
after that try CL7, if can set 1600 Cl7 with low voltage (1.52Vdimm) than you ram is superior

so far, this is the best i can do to my ram, cant even set at CL8, raise voltage to 1.78v also BSOD, dont know what to do now, any advice?

poison advice : change to other ram. winova xtune 1600CL11 1.5V can set 1600 CL7 @ 1.5XVdimm or 21XX CL9 1.65Vdimm
or you can try corsair dorminator.

btw don't go over 1.7Vdimm. not suitable for 24/7
er.. you can try increase your cpu-nb clock. btw you using divider 1600 for the ram or you increase the FSB?
